Data Format and Quality issues on Mac

[valenotary]

• When I just use frame.data().data_u32() to try to preview the image retrieved from the camera, The colors are not accurate -- when I started fiddling with the byte order, I came to the conclusion that the buffer data on my M3 mac was being returned in BGRA format. I believe maybe the buffer preparation code is not taking platform endianness into account?
• Even when I got the data format correct after fiddling, I noticed that the image is a lot darker than what the camera can perceive (Attaching a screenshot as a sample). Could the AVFoundation camera code be losing data, or is this expected?

  • I've tried artificially brightening the image via bitmasking, it remedies the issue a little bit but curious why it is just darker than normal...

Ok I at least figured out a way to remedy the second one -- turns out the M3 camera needs a warm up period of at least 3 seconds, If I sleep the thread until at least that point then the frame will return a full quality image... I'm curious do the other backends have this behavior of not "warming up" or is this just Mac ?
